“…Sliding mode control (SMC) is a robust and simple control scheme with a dynamic behavior [85] that was developed in 1977 by Uktin for parametric variations and internal and external unknown disturbance in variable structure systems [86]. SMC applications for WECS start with first-order SMC paradigms, as reported in the literature by [87][88][89][90][91]. First-order SMC schemes are subjected to inherent undesirable phenomena with finite amplitude and frequency called chattering [92].…”

“…The authors in [105] combine the attributes of the super twisitng control structure and fractional-order control theory. The author improves the FTSMC performance by using the equivalent terms in ( 89), ( 93), (91), and the super-twisting-based switching control law given in Section 5.2. The operational diagram of FOTSMC is shown in Figure 12 and the reviewed techniques are presented in Table 9.…”

The technological development in wind energy conversion systems (WECSs) places emphasis on the injection of wind power into the grid in a smoother and robust way. Sliding mode control (SMC) has proven to be a popular solution for the grid-connected WECS due to its robust nature. This paper reviews the enhancement trends in the integer-order SMC (IOSMC) and fractional-order SMC (FOSMC) schemes reported in reputed journals over the last two decades. This work starts with a mathematical description of the wind turbine, generators, grid, and SMC and its variants available in literature. A comprehensive literature review is tabulated that includes the proposed errors, sliding surfaces, typologies, and major outcomes. Moreover, a comparative analysis of the integer-order and fractional-order SMC and its variants is also presented in this paper. This paper will provide insight for the researcher working in the WECS and will serve them in the selection and exploration of the most appropriate control schemes for quality wind power extraction. The concise mathematical proofs of the IOSMC, FOSMC and their variants will also serve the researchers in selecting the relevant sliding surfaces control laws for their research tasks. This paper also provides a comparative analysis of IOSMC, FOSMC, and fuzzy-FOSMC in terms of chattering reduction, robustness, and computational complexities using mathematical theories, simulation carried out in Matlab/Simulink, and a processor in the loop (PIL)-based experimental environment.

“…Apart from these intelligent techniques, variable structure sliding mode control (SMC) has gained increased attention for the DFIG-based WECS owing to its robust nature against both modeled and unmodeled external disturbance, fault scenarios, parameter variations, simple structure, low parameter sensitivity and easy implementation for wind extraction [19], direct power control [20], and maintenance of DC voltage [21]. A number of SMC techniques have been proposed in the literature [22][23][24][25][26]. A novel experimental based SMC has been proposed in [27] using simplified vector control of the DFIG-based WECS.…”

A Super Twisting Fractional Order Terminal Sliding Mode Control for DFIG-Based Wind Energy Conversion System

et al. 2020

The doubly fed induction generator (DFIG)-based wind energy conversion systems (WECSs) are prone to certain uncertainties, nonlinearities, and external disturbances. The maximum power transfer from WECS to the utility grid system requires a high-performance control system in the presence of such nonlinearities and disturbances. This paper presents a nonlinear robust chattering free super twisting fractional order terminal sliding mode control (ST-FOTSMC) strategy for both the grid side and rotor side converters of 2 MW DFIG-WECS. The Lyapunov stability theory was used to ensure the stability of the proposed closed-loop control system. The performance of the proposed control paradigm is validated using extensive numerical simulations carried out in MATLAB/Simulink environment. A detailed comparative analysis of the proposed strategy is presented with the benchmark sliding mode control (SMC) and fractional order terminal sliding mode control (FOTSMC) strategies. The proposed control scheme was found to exhibit superior performance to both the stated strategies under normal mode of operation as well as under lumped parametric uncertainties.

“…Besides these techniques, different controls are used to control the active and reactive power of the DFIG-WT system. These controls can be classified into hybrid controls [29][30][31][32], intelligent controls [33][34][35], linear controls [36,37] and non-linear controls [38][39][40][41][42]. The use of these controls leads to obtaining an electric current of acceptable quality with the presence of ripples.…”

This work presents the implementation of direct active and reactive powers control (DARPC) with nonlinear controllers (synergetic controller (SC) and super twisting algorithm (STA)) for the rotor side converter of doubly-fed induction generator (DFIG) connected to the multi-rotor wind turbine (MRWT) system, as an alternative to the DARPC technique with STA controllers. In this work, DARPC is based on the nonlinear controllers and space voltage vector technique. Modified space vector modulation (MSVM) technique is applied to compose fixed-switching-frequency DARPC strategy, which replaces the switching table and hysteresis comparators technique in classical DARPC technique. DFIG's mathematics model and the two control techniques are given, and the simulations of DFIG based on DARPC-SC and DARPC-STA are made separately by Matlab software. In this work, two tests are proposed in order to verify the behavior of the proposed strategies, where the comparison between the strategies is in several aspects such as current quality, traceability of references, robustness, and ripple ratio. Simulation results show that the strategy based on synergetic control is better in terms of response time, ripple ratio, and electric current quality compared to other strategies.
